WHAT IS SUPER FERRITE STAINLESS STEEL?

*It is a kind of ferrite stainless steel which contains low carbon ,Nitrogen and other chemical element.

*C+N≤120ppm -400ppm(250ppm,150ppm).

 

CHARACTERISTICS

*With very low carbon and nitrogen-meet the requirement of processing and performance

*Niobium titanium dual stabilization-improved welding performance

*Chromium content:low chromium(10.5-15%),chromium(15-22%)and high chromium(22-32%);

 

ADVANTAGE

*Good abilities of stress corrosion, all kinds of localized corrosion,antioxidant corrosion(including high temperature oxidation resistance).

*Low density

*Good thermal conductivity: It is 30%-50% higher than Austenite. Small coefficient of thermal expansion: It is 30%-40% less than Austenite.

*Big elastic modulus

*Good processing properties

*Easily bending, stamping, curling, pinin, cold forging and machining.

*Excellent deep drawability
